On October 20, when South India’s first Metro chugs in, the journey will be one that has used a wide range of the latest technologies used by metro rail systems worldwide. “The Bangalore Metro, in terms of technology, is comparable to any metro rail system in the world — in Europe, USA or China — and is even ahead of some of them,” BMRCL MD N Sivasailam said. He said Bangalore Metro runs on the ballastless track system used by 70% of the world’s metros. In layman’s language, this means the track does not require stones used on traditional broad gauge track systems to build the track and run the train, as the load is lower than that of a conventional train. The tracks are laid on a concrete slab after assessing the engineering factors. Stones on the conventional track help in balanced construction, while in metro systems concrete slabs are enough,” he said.The advantages of ballastless (stoneless) track systems are faster travel, longer lifecycle of the track, ride comfort, and no maintenance. Even at speeds of over 300km/h, your coffee will stay in your cup.
STANDARD GAUGE The Bangalore Metro is standard gauge, a system used by most metros worldwide. Narrower than the broad gauge, it allows for greater manoeuvrability, easy ride along curves, laying of tracks even on narrow stretches and control. The standard gauge has a track width of 4ft, 8.5inches, or 1,435mm, while the Indian broad gauge is 5ft, 6inches, or 1,676mm.
ROLLING STOCK The rolling stock (coaches/cars) are three stainless steel-bodied wagons. Though equipped with automated functions, the train will be under the driver’s control. The seating capacity per train is approximately 1,000, giving more floor area to standing passengers. The coaches are world-class, manufactured by Hyundai Rotem Korea and Mitsubishi Electric Company. BEML has the licence to manufacture coaches in Bangalore. While Mitsubishi supplied traction for the coaches, Hyundai Rotem supplied the rolling stock and BEML the coaches.
POWER IN THIRD RAIL Electricity for the train will run on a third rail next to the main track. It has an opening at the bottom at points from where the train draws its power. The third rail is covered with a yellow shroud, and a person falling on the track won’t be electrocuted. ABB will design, supply, install and commission four substations to receive and distribute electricity at 66/33 kV, as well as auxiliary and traction substations. ABB will provide an integrated network management, or SCADA (Supervisory Control And Data Acquisition) system to monitor and control installations.
TECH AIDS FOR PASSENGERS Cameras will be installed inside the train as well as stations, and people’s movements will be monitored by an operations control centre at Byappanahalli. In case of any help or emergency, the control room will be able to see what went wrong. Trains will be Wi-Fi enabled, so passengers can use laptops, tablets as well as mobile internet. Passengers will have emergency voice communication with train staff through a speaker system. Passengers can press a call button to communicate anything urgent to the driver or control centre. Help will be at hand at the next station. The integrated control centre will have direct communication with trains and stations which will be CCTV-fitted with visual and audio service information. Bangalore Metro also has automatic train supervision, protection and operation systems — if there’s a train on the same track ahead, the approaching train will sense it and come to a halt at a safe distance. BMRCL officials said the only aspect that could have been automated but was not, was the opening and closing of doors. “We felt the driver needs to be alert. If everything is automated, the driver need not be in the train. So we’ve manually given the driver the option to open and close doors,” they said. Ticketing, too, is completely automated with just a swipe of the ticket, token or card at a particular point near the entry and exit, enabling the gates to open and close.

Congratulations Bangalore. Also let us not forget the sacrifices poeple made by giving away their land for this project. When such projects come someone has to give up his land and for us its always better if its not ours..Hope they all were taken care off well. Its others in the neighbourhood who benefit with appreciated prices. Thank you.
